Endothelial NOS (eNOS), also known as nitric oxide synthase 3 (NOS3) or constitutive NOS (cNOS), is an enzyme that in humans is encoded by the NOS3 gene.[1]

Endothelial NOS is a nitric oxide synthase that generates NO in blood vessels and is involved with regulating vascular tone by inhibiting smooth muscle contraction and platelet aggregation. A constitutive Ca2+ dependent NOS provides a basal release of NO. eNOS is associated with plasma membranes surrounding cells and the membranes of Golgi bodies within cells.

Clinical significance

Variations in this gene are associated with susceptibility to coronary spasm.[2]

An association between a polymorphism in the gene and late-onset Alzheimer's disease in Chinese have been reported.[3]

Interactions

Endothelial NOS has been shown to interact with CAV1,[4] HSP90AA1[5][6][7] and GUCY1B3.[5]
